Lucent Technologies Inc. announced Wednesday a breakthrough it hopes will improve the quality and lessen the cost of wireless networks.
Researchers in Lucent's Bell Labs have created what they believe are the first all-silicon chips for the receivers in base stations that get radio signals from mobile devices, such as cell phones or handheld computers.
The receivers generally in use now have 10 to 20 chips made of gallium arsenide, which has been considered the best material to handle a wireless network's complicated tasks.
Lucent said the system, which employs just three silicon chips, is 100 times smaller. Plus, the chips are 10 to 100 times less expensive.
The breakthrough, which will be employed in Lucent's next generation of wireless networks over the next four or five years, will improve the quality of streaming media and other rich content for wireless Internet users, spokesman Steve Eisenberg said.
The development is "a move in the right direction" but just one of many steps necessary to speed the widespread rollout of wireless Internet transmitters, said Sean Badding, a senior analyst for The Carmel Group, a market research firm in Carmel.
"I don't see anything significantly changing that's going to drastically improve Lucent's position" in the short term, Badding said.
Lucent, based in Murray Hill, N.J., announced the new design at the International Solid-State Circuits Conference in San Francisco, a day after the struggling company revealed it was closing its small Silicon Valley research center in Palo Alto.<
